The reward for information in the search for Christopher Dorner -- the fired LAPD officer wanted in three shooting deaths -- increased Tuesday as agencies continued to follow up on more than 1,000 tips generated during the manhunt.

Investigative agencies have received more than 1,000 tips from public since the LAPD announced a $1 million reward Sunday, Lt. Andy Neiman said Tuesday morning.

The Los Angeles City Council approved a motion Tuesday morning to add $100,000 to the reward fund for information leading to the arrest and conviction of 33-year-old Dorner. His online manifesto identifies law enforcement agents and their family members as targets in a revenge plot, according to investigators.

"This is causing panic and havoc for a lot of people," said LA Councilman Dennis Zine. "There are potential victims throughout this region.

The Los Angeles County Board of Supervisors also approved a motion Tuesday morning to add $100,000 to the reward fund.

The Riverside County Board of Supervisors plans to consider a motion to offer a $100,000 reward on Wednesday.

Ex-LAPD Officer Wanted in Shootings

Dorner was identified Wednesday as a suspect in the shooting deaths of a couple, including the daughter of a former LAPD captain, in Irvine.

He was charged with murder Monday in Thursday's shooting death of Riverside Officer Michael Crain. The officer and a trainee were ambushed at a stoplight in Riverside, according to prosecutors.

At a Tuesday news conference, LAPD Lt. Andy Neiman was asked about the tips and reports that Dorner might have fled to Mexico. There have been no confirmed sightings of Dorner since the shootings Thursday in Riverside County, he said.

"Early on, we had information that (Dorner) had attempted to abscond with a boat in the San Diego area," Neiman said. "Indications were that he was possibly going down to Mexico. Based on that information, our investigators were preparing to follow up."

An affidavit filed Feb. 7 in federal court by the U.S. Marshal Service was "in preparation to assist" in that investigation.

"That in no way indicates Dorner was or was not in Mexico," Neiman said.

Neiman also addressed surveillance video that TMZ obtained from a Sports Chalet store. The video shows a man purchasing scuba gear, but authorities have not confirmed that the individual in the video is Dorner, Neiman said.
